Lab: Types of Reactions

Question 1

To test the first hypothesis, you measured the reaction rate for several different

Revolt · Accepted Answer

temperatures.

Question 2

The data showed that for higher temperatures, the reaction rate

Revolt · Accepted Answer

increases.

Question 3

To test the second hypothesis, you measured the reaction rate for several different

Revolt · Accepted Answer

particle sizes.

Question 4

The data showed that for smaller particle sizes, the reaction rate

Revolt · Accepted Answer

increases.

Question 5

The longer the reaction time is, the ✔ lessergreaterthe reaction rate is. Reaction time is

Revolt · Accepted Answer

lesser; Selection 1: lesser; Selection 2: inversely proportional

Question 6

The smaller the particle size, the lesser✔ greaterthe surface area. Therefore, particle size is

Revolt · Accepted Answer

greater; Selection 1: greater; Selection 2: inversely proportional

Question 7

proportional✔ inversely proportionalequal to surface area.

Revolt · Accepted Answer

inversely proportional

Question 8

What would you expect to happen if you raised the temperature of the water to 85°C? Check all that apply.

Revolt · Accepted Answer

The reaction rate would be faster than the rate at 65°C.; The reaction rate would be slower than the rate at 95°C.

Question 9

proportional✔ inversely proportionalequal to reaction rate.

Revolt · Accepted Answer

inversely proportional

Question 10

Your stomach is upset. You want relief – and fast! What actions could you take to speed up the reaction of the tablet? Check all that apply.

Revolt · Accepted Answer

heating the water even more; breaking the tablet into smaller pieces; heating the water and breaking the tablet at the same time
